This gene version is less likely to cause severe COVID-19

The new results show that people with a specific version of a gene are less likely to develop severe COVID-19. Earlier research had identified a specific group of genes, called the OAS1/2/3 gene cluster, as being involved in the risk for severe COVID-19.

One version of a gene in that cluster -passed down from Neanderthals, appeared to protect against serious disease, reducing risk by about 23%. Most of the research done before was on Europeans. Researchers are now seeing the same association of this genetic variant with less severe COVID-19 in people of African ancestory, according to a report published in Nature Genetics.

“The fact that people of African descent had the same protection allowed us to identify the only variant in DNA that actually protects against COVID19 infection. Jennifer Huffman, co-author of the study, made a statement.

OAS genes are involved in a cascade of effects that help cells fight viruses, the researchers said. Understanding these genes and their impact on COVID19 risks could aid in the development of future drugs, they added.

Fewer Delta breakthroughs with Moderna vs Pfizer/BioNTech

When the delta variant coronavirus was widespread in the United States, recipients of two doses of Moderna’s mRNA vaccine (MRNA.O) were less likely to have breakthrough infection and were slightly less likely to be hospitalized than recipients of two doses of mRNA vaccine from Pfizer and BioNTech, found a large study.
